Hello. Prof. Yan. I have some questions.
1)
I and my lab member simultaneously calculated ReHo values in the same fMRI data using different version of the dpabi (ex. DPABI_V6.1_220101 VS DPABI_V8.2_240510/ actually dparsf-A in the dpabi).
we applied the same batch file including slice-timing, realignment, new segment+DARTEL, Nuisance covariate regression(polynomial trend:1), Friston 24, add mean back, Normalize(by DARTEL), band-pass filtering, ReHo cluster 27.
However, the results seem to be different(When we click the same coordinates(x,y,z) in the ReHo map of the same subject, the ReHo value is different).
I'd like to know if these results are due to different versions of dpabi. And if so, what steps might have caused these differences?
2)
When I took the dpabi camp a few years ago, I heard that seed-based FC (seed to all vertex analysis) in dpabisurf was too computationally intensive to be feasible. Now, I am wondering if it does not still support this function in the dpabisurf.
I'm looking forward to hearing from you. Thank you~
